DONALD ELDER, OF ONEHUNGA, NEW ZEALAND.

WIRE-WRAPPING MACHINE.

Specification of Letters Patent.

Application filed January 18,

To all whom it may concern Be it known that I, DONALD ELDER, a citizen of the Dominion of New Zealand, and residing at Onehunga, in the Provincial District of Auckland, in the Dominion of New Zealand, have invented certain new and useful Improvements in fire-Trapping Machines, of which the following is a specification.

The invention provides a machine for binding together two or more wires and is particularly useful for securing wire netting to fencing wires.

According hereto a binding wire is fed by a pair of rollers through a jaw which receives the wires to be bound together. By the turning of a handle a wheel mounted in the jaw, and having a gap which admits the wires to approximately its center, is re* volved and a laterally projecting pin caused to engage the binding wire and coil it the desired number of times around the wires to be bound together. A cam-operated cutter is provided to sever the binding wire and after such a wire has been properly coiled about the wires to be bound together the machine is removed to another place and the operation repeated.

I will now describe the details of my invention by the aid of the drawings wherein Figure 1 is a plan, Fig. 2, a side elevation, Fig. 3, a part sectional elevation with a wheel removed, Fig. 4, a cross sectional elevation on line 4 4, Fig. 3 showing grooved feed rollers, Figs. 5 to 8 inclusive are side sectional elevations showing part of the apparatus. Figs. 9 and 10 are front end sectional elevations of the gap wheel and parts, and Fig. 11 is a front elevation showing wire netting bound to a wire of a fence. Fig. 12 is a detail plan view of the gap wheel. Fig. 13 is an elevation of said wheel.

The binding wire 1 (see Figs. 1 to 3) is passed through a central hole 2 in the handle 3 and between the feed rollers 4 and 5 journaled in the frame 6 of the machine and having corresponding grooves in 'their circumferential peripheries to receive it. It then passes through a die 7 and longitudinally through a jaw 8 having a projecting lip 9 by which the wire is directed upwardly. A hand wheel 10 mounted upon a pin 11, fixed in the frame, is revolved by a handle 12 and has a segment of gear teeth which periodically engage with the ,pinion Patented Mar. 19, 1912.

13 liXed upon a spindle 14 of feed roller 4 which roller has gear teeth engaging with similar teeth of the feed roller 5. The spindle of the roller 5 is free to move in slots 43 and 44 in the frame. A spring 45 in a recess in the frame hears upon a bracket 5", which carries the spindle of the roller 5 (see Fig. 4) to permit said roller to move downward in ease sulliciently thick binding wire is used. A bevel wheel 15 upon the side of the wheel 10 is in gear with a bevel pinion 16 upon a spindle 17 revoluble in the frame and having a bevel pinion 18 upon the opposite end gearing with the bevel pinion 19 upon the face of the spur wheel 20 which revolves upon a spindle 21 fixed in the jaw 8 and is in gear with the gap wheel 23 rotatably mounted in the end of a lever afterward referred to. The gap wheel has a gap 25 from its circumference to beyond the center', to receive the wires 26 and 27 which are to be bound together, and the jaw has also a gap 28 to permit the wires to pass axially through the center of the gap wheel. A projecting flange from wheel 10 forms a ring cam 29 which operates a lever 3() pivotally supported upon a pin 31 passing through a stud 32 projecting from the frame. The gap wheel is revolubly mounted on the forward end of the lever so that when the lever is operated b v the cam the gap wheel (which has a relatively wide face so that it remains in gear with wheel 20) is moved laterally. The lever is pressed outwardly by a spiral spring 46. A pin projecting eccentrically from the gap wheel has a friction ring 34 adapted, when said wheel is shifted laterally and rotated, to engage with the binding wire 1 and to bend it in a spiral coil around the wires 26 and 27. To said pin 33 is also attached one end of a leaf spring 47 against which said binding wire bears. rlhe wheel 10 has also a cam upon the face opposite to cam 29, and arranged to engage a pin 36 and thereby to operate a lever 36 pivoted upon a pin 37 in the frame and having a cutter 38 at its end projecting over the face of the die 7 through which the binding wire passes. The lever is pressed away from the die 7 until operated by the cam, by a spring 40. A projection 41 from wheel 20 is arranged to engage in the gap 25 at each rotation of wheel 20 and to continue the rotation of the gap wheel which would otherwise come to rest through the absence of teeth in the gap.

In operation the binding wire is pushed through the handle 3 and hand wheel 10 continuously turned by its handle until a binding has been effected the wire 1 being passed by feed rollers through the die 7 until it projects beyond the lip 9 as shown in Figs. 1 and 3. The wires to be bound together are passed through the gap in the jaw and also the gap in the wheel 23 (see Figs. 9 and 10). Cam 29 is timed to operate lever 30 by pressing the rear end thereof outwardly and the gap wheel is moved laterally so that the ring upon the projecting pin 33 engages the binding wire (which is held from one end by the now stationary feed rollers) and bends its forward end ina spiral coil around the wires 2G and 27. The cam 29 is shaped so that the gap wheel gradually returns to its normal position under the influence of spring 46 and the bending of the wire spirally is thereby facilitated. INhen the binding has been effected the cam engages pin 36 on lever 36a and the wire is severed by the cutter passing over the face of the die 7. The coiling and cutting of the binding wire is clearly shown in a series of steps in Figs. 5 to 8 while Fig. 9 shows the gap wheel in the position it occupies at the commencement of the coiling, and Fig. 10 when the coiling has been completed. Fig. 11 shows a piece of wire netting 42, the upper wire 26 of which is bound to the fencing wire 27.

Vhat I do claim and desire to secure by Letters Patent of the United States is 1. A machine for the purpose indicated, comprising in combination aframe, ahandle thereon, a pair of geared feed rollers, a pinion connected to one of said rollers, a hand wheel having a segment of teeth engaging said pinion, means for revolving the hand wheel, a lever, a cutter at one end thereof, a cam for operating the lever, a die through which the binding wire passes, a jaw in the frame, a gap wheel having gear teeth, a pin projecting from the gap wheel, a pinion in gear with the gap wheel, a tooth wheel upon said hand wheel, gears for driving the pinion therefrom, a lever on which the gap wheel is rotatably mounted, and a ring cam upon the face of the hand wheel for operating said lever, substantially as specified.
